RAILROAD-TIE.

Specification of Letters Eatent.

Patented Oct. 23, 1906.

- Applicat'ion filed June 9, 1906. Serial No. 321,057.

To all whom it may concern:

Be it known that I, WILLIAM 0. SMITH, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvementsin Railroad-Ties; and I declare the following to be a'full, clear, and eXact'description of the invention, such as will enable others skilled in the art to which it pertains -to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

"My invention relateslto' an improvement,

in railroad-ties shown in the accompanying drawings and more particularly set forth in the following specification and claims.

' In the drawings, Figure 1 is a side elevation of a concrete tie with arts broken away, showing the formation of the truss in reinforcing the tie, the rails being locked in posi* tion. Fi 2 is aplan view of the tie, showing it broien away to expose the truss. Fig. 3 is a perspective view of one of the conesleeves embedded in the tie. Fig. 4 is a similar view of the cone. 'Fig. 5 is a longitudinal vertical section. through a portionof the tie, showing details of construction. Fig. 6 is a perspective view of the rail-engaging clamp. Fig. 7 is a plan view' of the wearing plate or shoe located between the rail and the tie.

Fig. 8 shows a modification'of the means employed to secure the cone-sleeve in the concrete. I

The object of my invention is to construct a concrete tie in which great strength is ob tained at a minimum cost of construction, the details of whichwill be hereinafter explained. 4

Referring to the letters of reference shown in the drawings, A is the concrete tie, and B .which the bolt E passes, being secured by the nut f.

Attached to the cone-shaped sleeve 0 is aninverted annular cone 0 to rigidly secure'the sleeve in the tie. I

G is a wearing plate or shoelocated between the rail and the tie.

While I have shown the arms I) ofthe truss B closely embracing the sleeves C, they may merely encircle the sleeves], allowing for a Wall or filling of cement be ween the sleeve and the arms. It will be oisserved that the peculiar shape of the bar B erves as a truss,

giving great strength and rigidityto the tie.

The manner of assembling the parts to secure the-rails to the tie will be readily apparent from the drawings.

In Fig. 8 I haveshown a modificationof the means forsecuring the cone-shaped sleeves in the concrete in which two or more projecting strips or fingers are secured to the wall of the sleeve in place of the inverted an nular cone shown in Fig. 3.

Having thus describd'my invention, what I claim is:

1. A tie formed of concrete or cement, coneshaped sleeves embedded in the tie, cones housed within the sleeves having central openings for the passage of bolts to secure the rails to the tie, the bolts, and clamping devices engaging the flange of the rail secured by said bolts, substantially as described.

.2; A tic formed of concrete or cement, a suitable truss reinforcement, conashaped sleeves embedded in the tie, cones housed within the sleeves having central openings for the "passage of bolts to secure the rails to the tie, the railretaining bolts, and clamping devices engaging the flange of the rail secured by said bolts, substantially as described.

3. In a railroad-tie formed of concrete or cement, a truss member embedded in the tie, cone-shaped sleeves also embedded in the concrete, said sleeves having annular inverted cones secured tl'iercto to insure the sleeves against removal, a cone housed Within each sleeve having a central opening for the passage of bolts foncugaging the rail, the bolts, and suitable clamping devices secured by said bolts, substantially as described.

' 4. In a l'ailroarbtic formed of concrete or cement, a truss member embedded in thetie, cone-shaped sleeves also cn'ibedded in the cmicrete, said truss member provided with 1 arms encircling the cone-shaped sleeves,

cones housed Within the sleeves provided GEO with a central opening for the passage of a bolt, the bolts, and suitable clamning devices to engage the flange of the rail secured by said bolts, substantially as described.

5. In a railroad-tie formed of concrete or cement, a truss-shaped TGiIlfOTGQI'IlGIlh embedded therein, cone-shaped sleeves embedded in the tie, cones housed. Within the sleeves having central openings for the passage of with openings for the passage of the rail-retaining bolts, substantially as described.

6. A ra1lroad-tie formed of cement or concrete, and a longitudinal reinforcement embedded therein and. provided with an arm at each end.

7. A railroad-tie con'lposed of concrete or cement, a reinforcement embedded in the tie and provided with arms, elen'lents embedded in the tie upon each side of said reinforce n'ient, the aforesaid arms embracing said elements.

8. A railroad-tie composed of concrete or cement, sleeves embedded in the tie, each sleeve having a core, and a truss member embedded. in the tie and having engagement with said sleeves.

in testimony whereof l sign this specific tion in the presence of two witnesses.
